Effective Computer-mediated Communication Using Hypertext: Introducing Expanding Hypertext--Are They Adventurous?

Effective Computer-mediated Communication Using Hypertext

Despite the potentials of hypertext for extending the effectiveness of computer-
mediated communication, many expressed concerns in using hypertext, such as disorientation
and fragmented knowledge. Disorientation is the most frequently cited problem. It is
believed that the nonlinear nature of hypertext tends to foster disorientation among users
(Batra et al, 1993; Dias, Gomes, Correia, 1999; Hammond, 1989; Hammond & Allinson,
1989; Smith & Wilson, 1993; Kim & Hirtle, 1995; McDonald & Stevenson, 1996; McDonald
& Stevenson, 1999; Unz & Hesse, 1999; Rouet, Levonen, Dillon, & Spiro,1996).
In this paper, expanding hypertext, a new hybrid form of hypertext, was introduced
and examined in terms of its usability to address this problem. Expanding hypertext is a new
electronic text format that shows additional excerpts or modes inserted into the same page as
the hyperlink itself (Lee, 2001). It is designed to provide typical hypertext’s flexibility to
inter-link related information while maintaining a linear presentation of information. In this
way, individuals can explore presented materials based on their preferences while reducing
cognitive overload and disorientation.
The most important potential of hypertext is its ability to interact with each reader
differently. Therefore, the preferences, needs, and unique characteristics of individuals should
be investigated in accordance with the development and refinement of new technologies. In
order to identify what kinds of individuals can benefit from these new technologies,
adventurousness, a personal motivational characteristic, was measured to test whether
different types of computer texts interact with individuals’ adventurousness on their
preference and experience with a given text format.
